Formation of phenol-formaldehyde resins. Phenolic resins account for a large portion of phenol production. Under the trade name Bakelite, a phenol-formaldehyde resin was one of the earliest plastics, invented by American industrial chemist Leo Baekeland and patented in 1909. Phenol-formaldehyde resins are inexpensive, heat-resistant, and ...
Substituted Resorcinol Formaldehyde Resin Application: SF-282 PBM is modified resorcinol formaldehyde resin. SF-282 PBM is currently used in Russian tyre factories like Niznekamsky, Belaya Cerkov, Kursky, Moskovsky and others. During last years over 400 tons of resin has been produced and used in these plants.
Phenol Formaldehyde Glue. Phenol Formaldehyde glue is the most commonly used glue in WATERPROOF contruction panels, beams and including many of the marine plywoods. Here is a link to my page on Marine plywood standards and grades. It is not easily available to home builders because it needs high pressure and temperature to cure.
Abstract. This chapter reviews and presents a perspective of the special qualities of the resorcinol/formaldehyde resins as adhesives for wood and in a variety of other, commercial or potential uses, with the exception of their use as reinforcing resins and bonding agents in vulcanizable rubber compounds which was dealt with separately in Chapter 4.
The International Union of Pure and Applied Chemistry recommended the name Benzene-1,3-diol as the standard name for the substance, but it is more commonly referred to as resorcinol. It is obtained by fusing resins, or hydrocarbon secretions of plants, with potassium hydroxide. Medically, resorcinol is used as an antiseptic and as a disinfectant.
iii Summary Ion exchange using the spherical resorcinol-formaldehyde (SRF) resin has been selected by the U.S. Department of Energy's Office of River Protection (DOE-ORP) for use in the pretreatment facility
Resorcinol-Formaldehyde Resin "Russian Red" Endodontic Therapy Nathan W. Schwandt, DDS, and Tom G. Gound, DDS, MS Resorcinol-formaldehyde resin is a material used in endodontic therapy in many foreign countries. With immigration to the United States increasing, American dentists need to become familiar with resorcinol-formaldehyde therapy.

Aerodux 500 calls itself Resorcinol-Phenol-Formaldehyde, whereas Cascophen refers to its glue as Resorcinol-Formaldehyde. Since the claims from all manufacturers are similar in major traits I will not differentiate and when I say resorcinol or resorcinol formaldehyde I am not saying anything about a specific brand.
Kinetics Study of( Phenol-Resorcinol-Formaldehyde) Resin Jenan J. Mohammed Chemistry Department, College of Science, Basra University, Basra, Iraq Abstract This study concern kinetic reactions of phenol-resorcinol-formaldehyde and compare to kinetic reaction of the polymer phenol- resorcinol-formaldehyde.
Hydroxymethylated resorcinol (HMR), is a dilute, alkaline mixture of resorcinol and formaldehyde which continues to react. It forms a resorcinol-formaldehyde polymer in time but provides a coupling action between the wood and other resins that a common resorcinol-formaldehyde adhesive.
Interestingly, resorcinol is often used in polyurethane resins and other coatings as a UV absorber. Adhesive Chemistry: The earliest commercial synthetic resin based on a Phenol formaldehyde resin is sometimes called phenolic and had the commercial name Bakelite. It is formed from a elimination reaction of phenol with formaldehyde.
CURE RATE OF RESORCINOL AND PHENOL-RESORCINOL ADHESIVES IN JOINTS . OF AMMONIUM SALT-TREATED SOUTHERN PINE . BY R.E. SCHAEFFER, CHEMIST . INTRODUCTION . The rate at which adhesives cure has always been of importance to the wood industry. In a large measure, this factor determines the gluing requirements for the particular operation for
A brief overview on the preparation and properties of resorcinol–formaldehyde organic and carbon gels reveals very interesting features about their structural and performance characteristics. The resulting nanostructure was very sensitive to the various synthesis and processing conditions.
Resorcinol is an analytical reagent for the qualitative determination of ketoses (Seliwanoff's test). Resorcinol is the starting material for resorcinarene molecules and the initiating explosive lead styphnate. Resorcinol reacts with formaldehyde to form a thermoset resin which can form the basis of an aerogel. Related compounds
Resorcinol-formaldehyde (RF) resin was patented by the Savannah River National Laboratory  to remove cesium from highly alkaline wastes. The resin is a resorcinol (C6H6O2) formaldehyde (CH2O) condensation polymer. This resin has a strong preference for H+ and can be eluted by using acid to remove Cs+ and its competitors.
Phenolic, resorcinol and formaldehyde-based resin (PRF) thermosetting adhesives. Phenolic, resorcinolic and formaldehyde-based resin (prf) thermosetting adhesives are described by characteristics such as form, class and open time (minimum).

The formaldehyde gas dissolves in the demin water, yielding a formaldehyde solution of approximately 45% strength, which is then cooled and pumped to storage. In the resin plant, two stirred reactors are used to make urea-formaldehyde (UF) resin or melamine-formaldehyde (MF) resin in a batch process.
